Abstract
A fuel injector comprises a tip end containing a flat planar orifice member that is sandwiched between a seat member and a flow director member. The thin disc orifice member contains a pair of metering orifices that receive fuel that has been allowed to pass through the seat member by virtue of the unseating of the injector needle. The fuel is emitted from the metering orifices as two parallel streams that are parallel to the injector centerline. The flow director member contains a pair of holes having wall portions arranged to cause the flow streams to be emitted from the injector tip as two streams that diverge from the injector centerline without any additional influence on the metering.
